There were only 800 copies of the signed numbered Wind done. Here on The Collector's site, the value is a range between $950 and $1250, which I think is pretty accurate. There's one out on eBay right now for $1500 or best offer.

The value of Little Sisters (1250 copies printed) here on the site ranges from $450-$550 if the number is over 800 and $650-$800 if it is number 800 or below. Again, I think these valuations are pretty good. #110 is on eBay asking $795.
